Answer:
-4/9
Step-by-step explanation:
We first calculate the first bracket.
[2/3-(-4/9)]
= (2/3+4/9) (we cancel out the negatives)
= (6/9+4/9) (common denominator)
= 10/9
Then we convert -2 1/2 into an improper fraction.
-2 1/2
= -5/2
Finally we calculate the division by swapping the numerator and denominator of -5/2.
10/9 / -5/2
= 10/9 * -2/5
= -20/45
= -4/9 (simplify the terms)
In the given question , we have a function given , which is

And we need to find the value of y when x=5.
So we substitute 5 for x and solve for y, that is

And on rounding to the nearest tenths, we will get

So when x=5, y=0.4
Answer: 50 + 2x
Step-by-step explanation: It's pretty basic math, you have your flat fee ($50) and then you add your variable 2x. 2 is multiplied by x so you can figure out the amount that it costs to ride the rides.
